| 摘 要： | 系统研究了氙灯和高压汞灯照射下对硝基苯胺(PNA)在蒸馏水、人工海水和天然海水中的光化学降解情况.结果表明,PNA光降解速率会受到光源、溶液介质、温度、起始浓度、重金属离子、甲醇及过氧化氢浓度的影响.随着光源强度的增强、起始浓度的增大、温度的增高和过氧化氢量的增加,PNA在海水中光降解速率相应加快；然而甲醇的加入可有效...

| Abstract: | The photochemical degradation of p-nitroaniline(PNA) was systematically studied in distilled water,the artificial seawater and natural seawater under the radiation of high-pressure mercury lamp(HPML) and xeon lamp.The results showed that the photo-oxidation rates of PNA were affected by various factor including lamp-house,medium,temperature,PNA initial concentration,heavy metal ions,hydrogen peroxide and methanol concentrations,and were increased along in seawater also with the intensity of irradiance,tempe... |
